As a member of The National Federation of State High School Associations (NFHS), DIAA regulates the playing rules of, and conducts the tournaments for, fourteen sports. DIAA crowns thirty-six champions each school year.
Championship competition is sponsored in multiple sports for girls and boys as well as awarded in (coed) unified sports.
DIAA classifies teams for Division I and Division II in boys and girls cross country, boys and girls outdoor track, boys and girls soccer, and wrestling. New for Fall 2021, a football reclassification model with a three-tier classification system was approved by the DIAA Board of Directors in February 2021. This new three-their system is a change from the two-division format which has previously been in place for DIAA Football.
Schools were placed into three districts competing for three state championships. Districts were determined by geographic location. 3A Classification will have 11 teams in 2 districts, 2A classification consist of 21 teams in 3 districts and 1A classification will have 14 teams in 2 districts. The football reclassification allows for more uniformity among schools, provides relief with in-state scheduling, addresses safety concerns, and will increase student athlete participation and interest in football to provide more teams the opportunity to compete competitively.Information regarding these sports, such as relevant policies and tournament information, can be found by clicking the appropriate season on the right tool bar.
